Abstract
An iterative method for artefact reduction in X-ray computed tomography is applied to neutron tomography data of a massive copper cylinder with a central conical bore. The acquired neutron radiography projections are heavily influenced by a scattering contribution originating from the sample, thereby violating the exponential law of narrow beam attenuation. Because this leads to similar effects like beam hardening in X-ray computed tomography, we tested the performance of this iterative method mitigating artefacts in neutron tomography caused by a different physical process.
